Elisabethwarte, Observation tower on the Plattenberg in Weistrach, Lower Austria

The Elisabethwarte is an 18.5-metre tower on the Plattenberg (750 m) in the Grub district of Weistrach, Lower Austria. It has five storeys crowned with battlements, and above the portal hangs a bust of Empress Elisabeth carved by the sculptor Paul Kohl. Since 2017 the tower has been climbable on three sides, and 82 steps lead to the viewing platform.

A wooden lookout already stood on the Plattenberg in the 19th century. The present tower was opened on 23 September 1900, built by the Austrian Tourist Club's St. Peter/Seitenstetten section and named after Empress Elisabeth, murdered in 1898. In 1976 it passed to the Austrian Alpine Club's St. Peter in der Au section, and in spring 2017 a Leader project called Rock the Sissi renovated it and made it climbable on three sides.

The tower is named after Empress Elisabeth, assassinated in 1898, and was opened on 23 September 1900. Above the portal is a bust of the empress made by the academic sculptor Paul Kohl. In 2017 the Leader project Rock the Sissi renovated the tower and made it climbable on three sides.

The tower stands on the Plattenberg at 750 metres, in the Grub district of Weistrach near Kürnberg; the approach is on foot, and the 82 steps to the platform are climbed inside the tower. The three sides made climbable in 2017 are for climbing, not for the stairs.

In spring 2017 a LEADER project called Rock the Sissi renovated the tower and made it climbable on three sides, adding a climbing route to the historic structure. The project also produced a tourism plan for the rural area around the Elisabethwarte.
